Don't know age of gun, so sorry if this is in wrong forum.
I was at a gun show recently and somebody was selling a 5" blued Model 29, with a full lug. Said it was a Horton one of (500?), but I didn't notice any markings on the gun to so indicate. Of course, I didn't really look very closely, since I wasn't really looking for a 29. Also didn't really bother to look at condition. Asking price was about a grand, as I recall. Was this gun the real deal? All the Horton's I've seen are 3".
